Product speciﬁcation

Quad bus transceiver; 3-state; inverting

74HC/HCT242

DC CHARACTERISTICS FOR 74HCT

For the DC characteristics see

“74HC/HCT/HCU/HCMOS Logic Family Specifications”.

Output capability: bus driver

ICC category: MSI

Note to HCT types

The value of additional quiescent supply current (

∆I

CC) for a unit load of 1 is given in the family specifications.

To determine

∆ICC per input, multiply this value by the unit load coefficient shown in the table below.
